Fast, efficient, sustainable: hydrogen refueling of trucks with WALTHER-PRÄZISION

Environmental protection and drive technology using renewable energy sources are currently gaining in importance and will continue to do so in the foreseeable future. Electromobility and with it fuel cell technology or hydrogen as a sustainable energy carrier are increasingly used. These hydrogen-powered vehicles are not only emission-free and thus environmentally friendly, but also enable similar ranges as comparable vehicles with combustion engines.This makes hydrogen interesting not only for cars, but also for local public transport or long-distance transportation. Due to its high energy density, fast refueling and long range, hydrogen is particularly suitable for trucks. As a pioneer in H2 refueling technology, WALTHER-PRÄZISION develops and manufactures technical solutions for hydrogen applications and has made a significant contribution to setting standards for high-pressure hydrogen technology. Among other things, the specialist for coupling systems offers numerous products for H2 refueling of trucks.

Reliable H2 refueling system with emergency disconnect coupling for trucks

Hydrogen as an energy source in trucks has a number of advantages. These include, for example, the high energy density, which ensures that vehicles with hydrogen fuel cells can also transport large loads without significantly reducing their range. Furthermore, hydrogen refueling is significantly faster compared to electric charging processes and the truck is ready for use again in just a few minutes. Hydrogen is used for refueling in different aggregate states and at different temperature and pressure levels. WALTHER-PRÄZISION offers special refueling systems for gaseous hydrogen with pressures of 700 bar or 350 bar, whereby the high-flow (HF) variant is designed for temperatures down to -40 degrees Celsius. The H2 refueling systems from WALTHER-PRÄZISION have a very high flow rate with a low pressure drop and a refueling time comparable to conventional fuels. They are not only intended for trucks, but also for cars, forklift trucks, trailers or other larger consumers.

The WALTHER-PRÄZISION range includes several products linking the transfer of hydrogen from the fuel pump, the dispenser and the vehicle. These include the vehicle filling nozzle, the so-called nozzle, a suitable high-pressure hose package and the emergency disconnect device on the tank hose. In addition, WALTHER-PRÄZISION also offers a suitable parking station for the nozzle, which is adapted to the requirements of the vehicle.
